DETAILED DESCRIPTION OF THE INVENTION

The present invention is drawn to a portable sign which can be used toprotect stalled or broken down vehicles with passengers still on boardto prevent oncoming vehicles or traffic from colliding with the stalledvehicles. Such a sign could also be used to summon medical services, orto inform motorists of dangers ahead such as broken sharp objects in theroadway or an accident. The portable sign of the invention can be usedby law enforcement, construction crews and/or government officials toredirect traffic or provide warnings or messages. The portable signcould optionally be provided as an accessory to new vehicles. It isenvisioned that the sign can be used in government-issued vehicles, suchas emergency response vehicles or police cars for use in accidents orother public events where signage would facilitate emergency ornon-emergency government-essential information to motorists or thepublic.

Also included would be a portable sign usable by merchants and vendorsto aid in information to potential customers and store visitors. Such asign could be easily moved and/or positioned in such a way as tomaximize exposure of the sign and its message as necessary. Optionally,the sign could have an audio function. The sign can be linked toinventory-control software to automatically change the message accordingto how merchandise is moving. The linkage to the sign of the inventioncan be wireless or hard-wired. Alternatively, the message on the signcan be changed manually by a store employee or owner to display adesired message. The sign can be programmed to also say a message, playmusic or reproduce an advertising message. The portable mature of thesign allows it to be positioned in different areas or to be carried to alocation away from the store for additional advertising exposure. Thesign of the invention is also useful for travelling vendors such as foruse by crafters at craft shows, farm market vendors, street vendors,flea market vendors, garage sales, and the like.

Yet another embodiment of the invention is a portable sign provided asan accessory to new vehicles. The sign can be included as a factoryinstalled device that has its electronic and control componentsintegrated into a vehicle or it can be a dealer-installed feature whichis partially integrated into a vehicle prior to sale and/or delivery tothe customer. Alternatively, the sign system can be installed post saleby a mechanic or authorized installer.

An emergency communication system and method is provided which includescommunication from the computer components of the sign to a remotecommunication center or with emergency response vehicles and/orinformation agencies. The sign system would include communicationssoftware and hardware included with the sign, along with a transmittercapable of transmitting a signal to a remote location. The sign wouldthen be capable of transmitting a message either directly to emergencyresponse entities or to a central communications center which couldrelay the message to emergency response entities. The communicationcould also take place with an entity which can provide further motoristassistance information, such as information about an accident locationor construction to overhead highway signs, smart phone applications, GPSservices, to radio traffic reporting entities and the like. A beacon canalso be installed that would alert a driver if the sign is removed froma pre-set distance from the driver or vehicle, such as if the driverforgets to collect the sign and drives away, or if the sign is stolen. Aremote communication device could be carried on a key fob, be located inthe vehicle or be located inside a retail establishment to alert aperson to the location of the sign.
